Which material is commonly used for residential water supply lines?

Copper is commonly used for residential water supply lines due to its excellent properties that make it well-suited for plumbing applications. It is highly resistant to corrosion, which is crucial in ensuring the longevity and reliability of water lines. Additionally, copper has good thermal conductivity, allowing it to withstand fluctuations in temperature without damage. Its durability and ability to handle high pressure make it a preferred choice in many residential plumbing systems.

Moreover, copper pipes can be easily soldered and joined, providing secure and leak-proof connections. This material also has a natural antimicrobial property, helping to keep the water safe for drinking by reducing the potential for bacteria and other pathogens to thrive within the pipes. Consequently, copper’s combination of strength, durability, and safety qualities makes it the go-to material for ensuring efficient and clean water supply in homes.
